p—^3He弹性散射动量空间库仑作用的处理

Treatment of Coulomb Interaction in Momentum Space for p-￣3He Elastic Scattering

将Ｒ．Ｃｒｅｓｐｏ和Ｊ．Ａ．Ｔｏｓｔｅｖｉｎ提出的方法，推广应用于自旋的散射，研究了ｐ—３Ｈｅ弹性散射动量空间库仑作用的处理．计算了２００－５００ＭｅＶ的微分散射截面和自旋观测量，并将其结果与Ｖ—Ｐ方法所得结果及实验结果进行了比较，显示出这种方法与Ｖ—Ｐ方法相比可应用的角动量和动量转移的范围更宽些．

Applying the method proposed by R.Crespo and J.A.Tostevin to p-3He elastic scattering,we study the treatment of Coulomb interaction of momentum space.The differential cross sections and spin observables at 500 and 300 MeV are calculated with R=7fm.The present results are compared with those given in V-P method.It shows that the applicable range of angular momentum and momentum transfer in R-J method are wider than those in V-P method.
